Lower Ball joint

Hey guys.
I have a 1989 Honda Prelude and need to know if i need a new lower control arm or just a new lower ball joint. Because i am of the the junk yard to pick up the parts but not sure if i need full control arm with ball joint or just the ball joint.(ball joint is on front left wheel)

I also need a break hose for the back right wheel. Since i got 4 wheel sterring do i need a special one?

Thanks

you minus well get the whole lower control arm, no point in fighting with the ball joint to get it out, and if you have 4ws you dont need no special brake line i have 2 88 ludes both with 4ws and the brake line fit on my old non 4ws lude...good luck...wanna but a body kit from me from jet speed?msg me
